74 Basic Tasks: Creating a banner, Part 3
Checking for Flash Player
Most people who visit your website will have the Flash Player 6 or greater
plug-in installed. In rare circumstances, a visitor might not have the plug-
in installed. There are several different things you can do when a visitor
without Flash Player visits your site. When you have a site that uses Flash
primarily for functionality, you might want to send that user to a custom
page that links to the Macromedia site, where the user can download the
player.
The Check Plugin behavior in Dreamweaver enables you to check whether
visitors to your website have the Flash Player plug-in installed. After the
behavior checks for a plug-in, you can route the visitor to different URLs,
depending on whether they have the minimum required plug-in. For
example, if the visitor doesn't have Flash Player, you can open a page that
links the visitor to the Macromedia website to download the latest version.
1. In gnome.html, click inside the body tag (click between the "y" the
closing angle bracket) and open the Behaviors panel in Dreamweaver
(Window > Behaviors).
2. Click Add (+) and select Check Plugin from the behaviors pop-up
menu.
3. Select Flash from the Plugin pop-up menu.
4. Leave the If Found, Go To URL text box blank.
This text box controls which page the visitor with the specified plug-in
sees. Leaving the text box blank ensures that users stays on the same
page if they have Flash Player installed.
5. Type a URL into the Otherwise, Go To URL text box.
Specify an alternative URL for visitors who don't have the Flash Player
plug-in. Type noflash.html into the text box.
NOTE
There is a noflash.html document for you with the source files, included in
the sample files that accompany this tutorial; it's inside the finished folder.
Either save this document in the same folder as the gnome.html document
you're working on, or create your own file in this location. Ideally, you
would create a custom web page for users without Flash Player.
